Yep they bolt right on and the big block chevy heads are drilled for every intake manifold so swapping a late mod fuel injected chevy bb into an early veh is simple. There is a slight difference in the shape of the coolant passages head to block when using these vortec heads on an early BB it it isnt a issue but the other way around you can have some problems with coolant leaking into the lifter valley.
